VALVE.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed April 24, 1916. Serial No. 93,273.

To all whom it may concern:

Be it known that I, STEPHAN C. GYUR- CSINA, a subject of the King of Hungary, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to improvements in valves and particularly to that type adapted to be used in connection with steam heaters or radiators in which the returns pass through the same valve that admits steam.

The principal object of the invention is to provide means wherein radiators of the type commonly employed may be freed of water formed by condensing the steam therein, the same returning through the feed pipe to the boilers or trap direct and without the use of auxiliary valves of any kind.

Another object is to provide means which avoid noise, as Water hammering and crackling in the pipes, caused by relatively cool water in heated pipes.

These and other like objects are attained by the novel construction and combination of parts hereafter indicated and shown in the accompanying drawing, forming a material part of this specification, and in which:

Figure 1 is a partial side and partial sectional view of a valve, made in accordance with the invention. Fig. 2 is a top plan view of the valve disk, showing a portion of the stem in section. Fig. 3 is a bottom plan view of the same, and Fig. 4 is a sectional view, taken on line 4l1 of Fig. 2.

In the drawings, the normal course of the steam current is indicated by the arrow through the inlet pipe 10, the corresponding outlet pipe 11 here being shown at a right angle as is common in devices of this character. This compels the use of an angle valve 12, comprising a hollow body 1i having a seat 15 of relatively large diameter in which is a circular opening 16. Engaging with the body, opposite to the inlet pipe 10, is a valve bonnet 17, provided with a packing nut 18 at its top through which extends the valve stem 20, having at its extreme upper end, a knob or hand wheel 21. The bonnet 17 is internally threaded suited to the screw threads 22 on the central part of the stem. Below the threads the stem has a portion 23 extending downwardly and provided with an enlarged annular head 24, the same being received within a recessed opening 26, formed in the hub 28 of the valve disk 29, the disk being attached to the head of the stem in such manner that it may rotate thereon, but raised and lowered by actuation of the valve stem 20. r The area of the disk 29 is such as to suit the valve seat 15, the lower side of the disk having an annular recess 31 containing a ring 32 of elastic material adapted to form a tight joint with the seat when forced upon it by the valve stem. Also formed with the disk are lugs 35 through which passes a pin 36 by which a clapper plate 37 is hingedly attached and adapted, when pressure is applied on its lower side, to close the opening 33, through the center of the disk, in alinement with the stem 23.

In operation, when the valve is opened, and disk raised the steam will obviously flow through the pipe 10, the valve opening 16, body 12 and out through the pipe 11. When it is desired to out off the steam, the disk 29 is firmly pressed against the seat 15 and its pressure will cause the clapper plate 37 to cover the opening 30 so that no steam may pass through. But if the water from the condensed steam or other sources enters the pipe 11, it will pass downward through the openings 26 and 33, contacting with the upper side of the clapper plate 37, causing it to open so that the water may escape and return through the pipe 10, to the boiler or receiving trap.

It will be understood that the invention is not limited to the exact construction shown or to the purpose indicated, but that modifications may be made within the scope of the appended claims as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a valve of the class described, the

2. In a valve of the class described, the combination with a hollow body, a seatformed therein, a bonnet secured to said valve body opposite the inlet, of a stem screw-threaded to suit said bonnet and m0v-- able therewithin, means formed with said disk coiiperative with means formed on said stem whereby they are caused to operate ver tically as a unit, said disk being freely r0- tatable 0n the stem and having a central aperture formed therethrough and a clapper plate hingedly attached to the lower side of said valve disk adapted to cover the 10 mentioned opening, when pressed thereagainst.

I In testimony whereof I have signed my name to this specification.
